reach approximately 405 dBA, resulting in intermittent interference with typical <br /> existing residential and business acti�ities, as well as any on-site sensitive �ses <br /> developed during earlier phases of Precise Plar� buildout. Construction noise <br /> could ele�ate noise le�els at some locatians (tt�e nearest residences) by more <br /> than 5 dBA. <br /> Mitigation: Mitigation 13-2. Reduce project demolition- and canstructioR-perivd noise <br /> impacts on nearby residences (including the Broadway 7owers apartments and <br /> the mobile home park near the proposed recycled water pipeline route) and <br /> sensiti�e uses developecf on the de�elopment site during earEisr phases (e.g., <br /> child care center} by incorporating conditians in project demolitior� and <br /> construction contract agreerr�ents that stipulate the following conventional <br /> construction-period noise abatement measures: <br /> � Construction Plarr. Prepare a detailed construc#ion pla� identii}Iing the schedule fvr <br /> major noise-generating construct+on activities. The construction plan sha!! identify a <br /> procedure far coordination with nearby existing and on-site newly constructed noise- <br /> sensitive facilities so that constructio� acti�ities can be scheduled to �ninimize noise <br /> dis#urbance. <br /> ■ Construction Scheduling. Ensure that noise-generating canstructior� activity is limited to <br /> between the hours of 7:00 AM to 8:Q0 PM, Monday through Friday, and prohibit any <br /> construction during other hours which would ca�se any increase in ambient noise levels <br /> within a residential district. (Redwood City Municipa!Code Section 24.32) <br /> � Consfruction Equipment Mufflers and Maintenance. Equip all internal combustion <br /> engine-driven equipment with ir�take and exhaust mufflers that are in good condition and <br /> appropriate for the equipment. <br /> ■ Equipment Lvcatiorrs. Lacate statior�ary noise-genera#ing equipment as far as possible <br /> from ser�siti�e receptors when sensiti�e receptors adjoin or are near the construction <br /> site. <br /> ■ Corrstrucfion Traffic. Route ai! construction #raffic to and from the canstruction sites via <br /> designated truck roUtes where possib�e. Prflhibit car�struction-reiafed heavy truck traffic <br /> in residential areas where feasible. <br /> ■ Quref Equipment Selectian. Use quiet canstruction equipment, particularly air <br /> compressors, wherever possible. <br /> ■ Temporary Barriers. Construct solid plywood fences around construction areas to shield <br /> residences, operatio�al businesses, or noise-sensitive land uses. <br /> ■ 7emporary Noise Blankets. Temporary noise control bianket barriers should be erected, <br /> if necessary, a�ong building facades or around construction areas. This mitigation would <br /> an�y be necessary if canflicts occurred which were irresofvable by proper scheduling. <br /> (Noise canttal blanket barriers can be rented and quickly erected.) <br /> ■ Noise Disrurbance Coordinator. The City shall require projecf designat�an af a "Noise <br /> Disturbance Coordinator" who wouid be responsible for respanding ta any local <br /> ATTY/RE50.2898/PC RE50 RECONlMENDING S7ANFORD EIR tER71FICATION <br /> REV:48-15-13 Vli <br /> Page 24 pf 5fi <br />
